4.4 Adjusting Seastate

In heavy seas, more variations in heading will be detected, and

if the Wheelpilot tried to respond to all of these errors, it would

be overworked, causing unnecessary strain to the unit and

excessive drain on the batteries. Instead, it continuously moni-

tors the corrections applied over the course of a voyage and

allows a “dead band”, within which the boat can go off course

without constant corrections being made (Fig 4.6). The size of

the dead band is normally automatically adjusted by the

Wheelpilot to give the best compromise between course hold-

ing and battery consumption, but it can be set manually if

desired:

– In calibration mode, press TACK to toggle between Gain

and Seastate adjustment (indicated by the Port LED illumi-

nated). The Seastate level is indicated by the number of

audible beeps and flashes of the Nav LED. No beeps or

flashes of the Nav LED indicates that the Wheelpilot is set

to Auto Seastate.

– Use the Port ( ) and Starboard ( ) keys to adjust the

Seastate setting between 0 and 9. Selecting 0 will switch the

Wheelpilot to Auto Seastate.

– Press NAV to confirm settings and return to normal opera-

tion.

When Gain is selected, the Nav LED will flash and a repeated

sequence of beeps will be heard. The number of flashes and

beeps in the sequence indicates the level of the Gain setting.

Use the Port ( ) and Starboard ( ) keys to adjust the Gain set-

ting between 1 and 9 (Fig 4.5) -
